A judge today sealed all evidence in the case of a Highland Park teen accused of huffing a cleaning product before striking a family with her car, killing a 5-year-old girl.

Authorities say Carly Rousso, 18, lost control of the Lexus she was driving, careened across several lanes of traffic along Central Avenue in Highland Park and onto the sidewalk, striking a woman and her three children. Jaclyn Santos-Sacramento of Highland Park died in the Labor Day crash.

Rousso also faces a civil lawsuit filed by Jaclyn’s family, and the evidence in that case has also been sealed, Lake County Assistant State’s Attorney Ken LaRue said.

“We are just ensuring that she will get a fair trial,” said LaRue.

Officials have alleged that, before the accident, Rousso had inhaled fumes from a computer cleaning product, a practice sometimes known as "huffing." A canister of the cleaning product was found in her car, officials have said.

If convicted on all charges, Rousso faces a maximum of 26 years in prison, prosecutors have said.
